A few from Wales. ID hints welcome.

[Gerel]

Well you asked for it (you know who you are)

A few shots from a brief wander today.

These three I guess to be Cladonia ssp. the first was on a fallen branch, the other two on fence posts.


Next up this oak was covered in this

While this similar looking one was growing on an ash nearby

Finally another three on fence posts.



ID suggestions welcomed, also any hints on what features I should be looking for to make identification easier (I am a complete novice when it comes to lichen )

Cheers

Hi Gerel, from another complete novice, i think you are probably right with your first three being Cladonia sp,
the one on the oak tree, i think is a Pertusaria sp, probably multipuncta , but dont take my word for it i may be totaly wrong,

the others , no idea to the one on the ash , the last three look like they could be Parmelia sp, but its just a guess,

Ooh err eee ...... from another complete novice - yes the first three are all Cladonia's,

Image 2 - 'cladonia sp.on post' could be Cladonia squamosa
Image 3. 'Cladonia sp. on post ' could be Cladonia coniocraea

Very uncertain as to the oak and ash ones ......

Fencepost:
Image 1. 'on post post 3': I've quite a few similar that I've not managed to ID yet ....
Hypogymnia physodes / Hypotrachyna species could be worth checking but you need to see what the underneath of the lobes are like - thats a diagnostic for most of the foliose (leafy) ones

Image 2. 'On post 2': yes, could be Parmelia sulcata (in the middle of the previous image too)

Not much help I'm afraid - I seriously need to do a lichen identification course or find someone over here to go lichening with ......

Hi,

Gleditsa, the one on the oak does look like some of the Pertusaria ssp. on UKLichens thanks.

JennyS, I'll try to remember to get shots of the underneaths of the foliose jobs in future (when they're not covered in snow).

I agree with Jenny on the Cladonias. No. 1 is probably also C. coniocraea, but it is a bit young and key features are not visible.

The oak Pertusaria is P. pertusa - the "pepperpot lichen".
Difficult to make out the features of the one on ash, but probably the same.

On the fence post, Jenny is probably right with Parmelia sulcata, but I have a hunch it is P. saxatilis. We cannot see from the photo whether it is going to form soredia or isidia, and that is the critical distinction. P. saxatilis is better known on rocks, but it happily grows on acid-barked trees and old, acid fence-posts, usually in association with Hypogymnia physodes, which you have here.

I think the 3rd fence-post lichen is Pertusaria albescens. (Well-defined, disc-like soralia.)
